Détente
GCSE History détente: why the superpowers eased tension after Cuba, through SALT, Ostpolitik and Helsinki, and why Afghanistan in 1979 is taught as the thaw’s collapse.
Détente was a managed rivalry: shake hands over missiles, still fight through proxies — until Kabul ended the handshake.
The important bits
What you need to know
- 1
Détente means a relaxation of tension, not friendship. It grew from October 1962’s shock, the cost of Vietnam and the Soviet desire for Western technology and nuclear parity recognition.
- 2
The 1963 hotline and Partial Test Ban Treaty were early drips. The Nuclear Non-Proliferation Treaty (1968) added another. Real architectural détente is the 1970s.
- 3
West Germany’s Ostpolitik under Willy Brandt — Moscow Treaty 1970, Basic Treaty with the GDR 1972 — accepted two Germanys in practice to ease human contacts. Brandt kneeling at the Warsaw ghetto memorial (1970) was moral politics with a strategic aim.
- 4
Nixon went to China (1972) and Moscow. Triangular diplomacy pressured the USSR. SALT I (May 1972) froze some ICBM numbers and included the ABM Treaty — arms control, not disarmament.
- 5
The Helsinki Accords (1975) recognised European borders (a Soviet win) and included Basket III human rights (a long Western lever for dissidents such as Charter 77).
- 6
Limits: both sides kept huge arsenals; the Middle East (1973 war, oil shock) and Angola showed proxy competition continuing. Détente was Europe-heavy and cynical.
- 7
The Soviet invasion of Afghanistan (December 1979), plus the 1979 NATO Dual-Track decision on Cruise/Pershing, the Olympic boycotts, and Reagan’s 1980 election, are the standard “end of détente” bundle on GCSE specs.
- 8
Judgement: détente lowered the chance of a European nuclear surprise and froze Germany; it did not end the Cold War. Gorbachev, not Nixon, ended it.
Quotations worth analysing
Short evidence. Real method.
“We have a chance to make the world safer.”
Safer, not friendly. SALT I is a ceiling, not a hug. Keep the tone cool in your essay and you will sound like a historian.
“Change through rapprochement.”
West Germany would talk to the GDR to loosen it, not to convert it overnight. Human contacts as a slow weapon — later visible in 1989.
“Basket III is a time bomb in the Soviet empire.”
At the time many called Helsinki a sell-out of Eastern Europe. With hindsight, dissidents used the text. Consequence delayed is still consequence.

Why shake hands after Cuba and Vietnam
Nuclear parity made a first strike look like suicide (MAD). The USA wanted out of Vietnam’s political trap; the USSR wanted grain, machines and recognition as an equal superpower. China after 1969’s border clashes with the USSR gave Nixon a card. Détente is therefore multi-causal: fear, cost, and triangulation. Brandt’s Ostpolitik added a European engine Washington did not fully control. In 16-mark “why did détente happen” answers, put Cuba’s fright and the arms bill first, then Vietnam and China, then European Ostpolitik. Do not start with “they got nicer”. They got more scared and more tired, which is different.
Go deeper
What détente did not cover
Africa, the Middle East and, fatally, Afghanistan remained arenas of competition. SALT did not cover every delivery system; both cheated at the edges. Helsinki’s borders clause pleased Moscow while human-rights language annoyed it. When the USSR sent the 40th Army into Afghanistan in December 1979, Carter embargoed grain, boycotted the 1980 Moscow Olympics, and expanded aid to opponents — a symbolic and material end to the 1970s mood. Reagan then spoke of an evil empire and funded the Strategic Defense Initiative. Teach 1979 as a breaking point without pretending the 1970s were peace. Proxy dead already dotted the decade. Détente managed the central front; it did not civilise the Cold War.
See the idea in action
Question: “Détente was a genuine attempt to end the Cold War.” How far? Judgement: it was a genuine attempt to manage and limit the Cold War, not to end it. Support: SALT I, hotline, Brandt’s treaties, Helsinki’s talks. Challenge: arsenals remained, proxies continued, Afghanistan 1979, no agreement on Germany’s freedom. Conclusion: ending the Cold War required Gorbachev’s non-intervention in 1989 and Soviet collapse — a different project. Détente was a ceasefire in Europe’s nerves, not a peace treaty for the system.
Exam technique
Turn knowledge into marks
Name SALT I 1972, Ostpolitik/Brandt, Helsinki 1975, and Afghanistan December 1979 as the full stop. “They were friendly in the 1970s” will not mark.
Common mistakes
Do not give these marks away
- 01
Spelling it “detent” or confusing it with the 1930s. It is the 1960s–70s thaw.
- 02
Claiming SALT abolished nuclear weapons.
- 03
Forgetting that Vietnam and Africa were hot while Europe talked.
Which event is most often taught as ending the 1970s détente?
AThe Berlin Blockade of 1948–49
BThe Soviet invasion of Afghanistan in December 1979
CThe Spanish Armada of 1588
DJenner’s vaccination of 1796
Show the answer
The Soviet invasion of Afghanistan in December 1979. Carter’s response and Reagan’s later policies mark the freeze’s collapse. Détente had already been strained, but 1979 is the spec’s hinge.
Quick questions
If this is the bit you searched
What did SALT I actually do?
It limited certain categories of strategic weapons and restricted anti-ballistic missile defences. It did not scrap the arsenals. “Control” ≠ “disarmament”.
Was Ostpolitik a US policy?
It was West German, under Brandt, though it fitted a wider thaw. It shows Europe as an actor, not only a chessboard.
Why do some historians defend Helsinki?
Because dissidents cited Basket III. Short-term it looked like recognising Soviet conquests; long-term it gave a legal language of rights inside the bloc.
Did Cuba start détente on its own?
It started the learning (hotline, Test Ban). The architecture is 1970s. Periodise: aftershock, then structure, then 1979 break.
